Patented Oct. 3, 1939 UNITED STATES PATENT OFFICE GAS BURNER deceasedApplication April 10, 1936, Serial No. 73,707 Renewed April 25, 1938 7Claims. (Cl. 60--30) My invention relates to a new and usefulimprovement in a gas burner adapted foi` use in completing tne ecmbitionof gases which are exhausted from internal combustion engines and 5 hasfor its object the provisioniof a device of this class which will besimple in structure, economical of manufacture, durable, highlyeilicient in u and easily and quickly installed.

Another object of the invention is the provil sion' of a mechanismmounted in the exhaust manifold and so arranged and constructed as tofacilitate further combustion of the gases exhausted from an internalcombustion engine.-

Another object of the invention is the provi- 13 sion in a device ofthis class of a perforated member mounted in the exhaust manifold forthe reception of exhaust gases and the provision of blast delivery meanswhereby suflicient air may be delivered into the presence of the exhaust20 gases to assist in combustion.

Other objects will appear hereinafter.

'I'he invention consists in the combination and arrangement of partshereinafter described and claimed.

y The invention will be best understood by a reference to theaccompanying drawlng`which forms a part of this specification, and inwhich, Fig. 1 is a side elevational view of the invention with a partbroken away showing it mounted on :zo the engine.

Fig. 2 is a longitudinal. vertical, sectional view of the invention.

` Fig. 3 is a sectional view taken on line 3 3 of Fig. 1. 35 In thedrawing I have illustrated the invention used with an internalcombustion engine 9 having anl exhaust control valve III to control theflow of the exhaust gases to the exhaust port I I. l A number of thesevalves are, of course, provided 40 on the multi-cylinder engines butsuflicient is illustrated to indicate the nature of the invention.Almanifold I2 is mounted on the side of the engine block l and hasopenings I3 communieating with the exhaust ports II. Extending iflengthwise of the manifold is a hood-forming portion I5 whichcommunicates with the mani-v fold and also communicates with-a conduitI0 adapted to deliver air from the blower I1 which ais operated by meansof the pulley I8 and the 50 belt l). The communication of thehood-forming portion li with the interior of the manifold is through theopenings Il formed in the wall 30. Positioned in the exhaust manifold isa cylinder having perforations 2I formed therein and 55 closed at oneend with the perforated end wall 22. 'I'he opposite end abuts againstthe end wall 23 of the manifold I2. This perforated cylinder 20 isprovided with the openings I3' positioned opposite the inlet openings I3of the intake manifold I2, so that the exhaust gas will flow into the 5perforated cylinder 20. The air delivered from the blower will alsoenter the perforated cylinder 20 through the perforations 2| and minglewith the gases. Perforated partitions 24 and 25 are mounted in thecylinder 20. An outlet pipe 26 10 communicates through the opening 21formed in the end Wall 28 of the manifold I2.

The construction is such that as the hot and burning exhaust gases arepassed into the cylinder 20 the air delivered thereto will be delivered15 in such volume as to further assist combustion and thus effect acomplete combustion of the gases. In this way the kobnoxious odors whichare frequently imbued from internal combustion engines may be eliminatedand the noiseless op- 20 eration of the engine effected free from odors.

While I have illustrated and described the preferred form ofconstruction, I do not wish to limit myself to the precise details ofstructure shown, but desire to avail myself of such variations andmodifications as may appear within the scope of the appended claims.

Having thus described my invention, what I claim as new `and desire tosecure by Letters Patent is: 30
